research Analysis of hormone antagonists in clinical and municipal wastewater by isotopic dilution liquid chromatography tandem mass spectrometry
Researchers developed a method to detect hormone-blocking drugs in wastewater and found them in Beijing's sewage, suggesting they can survive sewage treatment.
research Endogenous steroid hormones in hair: Investigations on different hair types, pigmentation effects and correlation to nails
Body hair isn't a good substitute for scalp hair in steroid analysis.
research Premature Adrenarche
Early adrenal gland maturation in young children can be normal, but other serious conditions should be ruled out first.
research Revisiting hyper- and hypo-androgenism by tandem mass spectrometry
The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.
